Here we present the first light of the Single Star Scidar (SSS) at Dome C, during January 2005 and the first results obtained during the winter 2006. We recall the SSS principle, how it is designed to resist to very low temperatures and to be adjusted in a very simple way. No exemple of long period of observation can be given since the huge amount of data cannot be sent back to our laboratory to be offline processed, due to low data transfer available from Dome C. But, a short file is shown, which demonstrates the major contribution of the surface layer to the whole atmosphere optical turbulence. Almost 300 hours of observations have been taken successfully during winter 2006.
